First, you have to find out what's 7% of $80. So what you do is multiply 80 by 0.07, which leaves you with $5.60. Add 5.6 to 80 so you get 85.6. Now you have to find how much the 20% of 80 is. So you multiply 80 by 0.2, leaving you with 16. So you subtract 16 from 85.6, leaving you with 69.6. So the total cost of the skateboard would be $69.60.

the company sea esta has ten members on its board of directors. in how many different ways can it elect a president, vice-presid

Inessa [10]

There are 10 members on the board, so there are 10 ways to elect a president, 9 ways to elect a vice president, 8 ways to elect a secretary, and 7 ways to elect a treasurer.

This is because each position can be filled by any of the members, except for the position that the member is already filling. For example, the president can be elected from any of the 10 members, but the vice president must be elected from the remaining 9 members.

The company sea esta has ten members on its board of directors, so it has a lot of different options for how to elect a president, vice-president, secretary, and treasurer. One way to elect a president would be to have the board members vote on who they want to be president.

Another way to elect a president would be to have the members of the company vote on who they want to be president. There are many different ways to elect officers, and it really depends on the company and what they want to do.

The number which is express in each of the models as given in the image attached to the task content are as follows;

a). 1.37

b). 1.37

c). 1.37.

<h3>What numbers are expressed according to the given models in the task content?</h3>

It follows from the task content that the models describe that One flat represents 1 whole, One rod represents 1 tenth and one unit represents 1 hundredth.

It therefore follows from the task content that in each of the models, the algebraic sum of flat(s), rods and units as the case may be results in the value; 1.37 as the utmost number represented by the models.
